Comment (by errge):

 Johan, -march=native is a very interesting idea, thanks for bringing it
 up!

 If you have ideas about that, please open a new ticket for discussion.

 I'd like to keep this ticket/patch/feature request as minimal as possible
 and only about switching the default if others in the community agree.
 Implementing your envisioned -march=native seems to be a very useful thing
 to do, but a much bigger job...
